pub trait AbstractQuasigroup<O: Operator>: PartialEq + AbstractMagma<O> + TwoSidedInverse<O> {
    fn prop_inv_is_latin_square_approx(args: (Self, Self)) -> bool
    where

}

A quasigroup is a magma which that has the divisibility property (or Latin square property). A set with a closed binary operation with the divisibility property.

Divisibility is a weak form of right and left invertibility.

Divisibility or Latin square property

∀ a, b ∈ Self, ∃! r, l ∈ Self such that l ∘ a = b and a ∘ r = b

The solution to these equations can be written as

r = a \ b and l = b / a

where “" and “/” are respectively the left and right division.

Provided methods

fn prop_inv_is_latin_square_approx(args: (Self, Self)) -> bool where
    Self: RelativeEq, [src]

Returns true if latin squareness holds for the given arguments. Approximate equality is used for verifications.

a ~= a / b ∘ b && a ~= a ∘ b / b

fn prop_inv_is_latin_square(args: (Self, Self)) -> bool where
    Self: Eq, [src]

Returns true if latin squareness holds for the given arguments.

a == a / b * b && a == a * b / b
